The wavy lines mimic a flag waving wildly in the wind while the durable vinyl can stand up to a number of elements and still keep on shining. Each sticker is cut by a computer from the same grade of vinyl used to make signs. That means these stickers are going to stick with you for a very long time without fading or otherwise falling flat. Stick them to your windows, doors, vehicles, notebooks – anywhere you want a firm reminder of how cool it is to be American.
